Explanation

FAST Cache Mechanism: FAST (Fully Automated Storage Tiering) Cache in Dell Unity systems temporarily holds frequently accessed data to improve read and write performance. The data moved to FAST Cache is managed in chunks to optimize storage efficiency and Chunk Size for FAST Cache: Dell Unity systems use a chunk size of 128 KB for data moved to FAST Cache. This size is optimized for balancing performance and storage management overhead. Smaller chunks, such as 32 KB or 64 KB, might increase management overhead, while larger chunks like 256 KB could reduce the granularity of data movement and efficiency.
